Objectives : The purpose of this study is to investigate the etahnol extract of Saururus Herba and their dermal boiactivity properties related to cosmeceuticals such as depigmentation and radical scavenging effect. Methods : Using B16/F10 Melanin cells, we measured depigmentation effect of the etahnol extract of Saururus Herba. Antioxidant activities of the etahnol extract of Saururus Herba were determined by DPPH radical scavenging activity. Results : The etahnol extract of Saururus Herba showed considerable radical scavenging activity($SC_{50}$ : 25 ${\mu}g$/ml). Antioxidant activity is in a dose dependant manner. The etahnol extract of Saururus Herba down-regulated melanin synthesis effectively. B16 cells incubated with the etahnol extract of Saururus Herba showed reduces melanin formation and tyrosinase activity. The etahnol extract of Saururus Herba alone markedly suppressed melanin content and tyrosinase activity. Conclusions : These results suggest that the ethanol extract of Saururus Herba is a potent depigmentaion agent and it may be a candidate for antioxidant agent.

This study was performed to determine the cytotoxic effect of methanol extract from medicinal plants. 1. The cell viability was determined by MTT method. Their cytotoxic activities against three cancer cell lines such as A549, MDA-MB-231 and SNU-C4 cell line were tested. 2. Among them, The methanol extract of Saururus Ohinensis Bail showed the strongest cytotoxic effect against SNU-C4 cells. These results suggest that the methanol extract of Saururus Ohinensis Bail possessed a potential antitumorous agent. 3. The free radical scavenging activity using DPPH method was the strongest of Saururus Chinensis Bail extract.

Rhizoctonia stem rot of Saururui herba [Saururus chinensis (Lour) Baill] was observed during plantations from 1996 to 1997 in Chungbuk area. Infected plant showed damping-off and stem rot at soil line. The causal fungus of stem rot isolated from the infected plant was identified as Rhizoctonia solani according to the criteria based on the cultural and morphological characteristics. The stem rot of Saururi herba caused by Rhizoctonia solani was first described in Korea, and the name the“Rhizoctonia black stem rot”is proposed.

For the investigation of bioactive natural products with analgesic activity, we have evaluated various extracts of Saururi Herba (Saururaceae), which has been used in traditiona l medicine for edema, beriberi, jaundice, turbid urine, carbuncle and furuncle. The diethylether extract of this plant was found to show a significant analgesic effect on writhing syndrome in mice. Using bioactivity-guided separation of the diethylether extract, analgesic constituent, (8S, 8`R, 7R, 6`R)-2'-oxo-4,5: 4',5'-bis(methylenedioxy)-${\Delta}^{1,3,5,3'}$-8.8', 7.6', 2.O.5'-neolignan(sauchinone) was isolated and structurally identified by physico-chemical properties and spectroscopic evidences. This compound has good analgesic activity with lower toxicity, as compared to other antipyretic-analgesic drug(acetaminophen).

In our search for bioactive natural products with antitumor activity, we have valuated various extracts of Saururi Herba (Saururaceae), which has been used in traditional medici ne for edema, beriberi, jaundice, turbid urine, carbuncle and furuncle. The hexane extract of the aerial part of this plant was found to show a potent cytotoxicity against several kinds of cultured human solid tumor cell lines (AGS, A549, HCT15, SKOV3, HEP-3B) in vitro. Using cytotoxicity-guided chromatographic separation of the hexane extract, cytotoxic constituent: 10-aminomethyl-3-hydroxy-4-methoxyphenanthrene-carboxylic acid lactam, was isolated and structurally identified by physico-chemical properties and spectroscopic evidences.

본 연구에서는 전통적으로 약으로써 이용되었거나 민간요법으로 사용되던 식물을 문헌고찰을 통해 40여종(자생식물 26종과 생약식물 14종)을 선발하여, 폴리페놀과 플라보노이드 함량 측정 및 DPPH 라디칼 소거능을 측정하였다. 자생식물인 비수리의 폴리페놀(228.90 mg/g extract)과 플라보노이드 함량(90.15 mg/g extract)이 가장 높았으며, DPPH 라디칼 소거능(75.69%)이 모두 높게 나타났다. 감나무와 관중의 폴리페놀 함량(감나무 112.98 mg/g extract, 관중 121.46 mg/g extract)과 플라보노이드 함량(감나무 46.10 mg/g extract, 관중 58.69 mg/g extract)은 높은 편은 아니었으나, DPPH라디칼 소거능은 각각 72.87%와 79.50%로 가장 높게 나타났다. 생약식물에서는 삼백초의 총 폴리페놀함량이 194.60 mg/g extract, 애엽이 203.93 mg/g extract로 폴리페놀 함량이 높았으며, DPPH 라디칼 소거능(삼백초 66.27%, 애엽 66.22%) 또한 높게 나타났다. 그러나 삼백초와 애엽을 제외한 12종류의 생약식물의 DPPH 라디칼 소거능이 50% 미만인 것으로 조사되었다. 최근에 다양한 자생식물과 약용식물의 폴리페놀, 플라보노이드 함량 및 기능성 탐색에 대한 연구가 많이 진행되고 있지만, 아직까지도 연구되지 않은 무수히 많은 식물 소재들이 많아서 지속적인 연구가 필요하다. 본 연구 결과, 그 동안 대중화 되어있지 않았던 식물 소재들의 기능성 소재로의 가능성이 새롭게 조명 될 수 있을 것으로 사료되며 이와 관련된 의약품, 미용제품 및 건강보조식품 등의 개발에 기초자료로 이용될 수 있을 것으로 기대된다. 향후 본 연구에서 조사한 자생식물과 생약식물 중 총 폴리페놀함량과 플라보노이드 함량이 높고, DPPH 라디칼 소거능이 뛰어나게 나타난 몇몇 식물에 대한 심도 있는 연구가 필요할 것으로 판단된다.
